A geological event set in the middle part of the Chuanlinggou Formation was demonstrated by a series of macroscopic, microscopic, and geochemical records. The macroscopic event structures include interformational slumps and faults, sand-liquefaction, carbonate brecciation etc. ; the microscopic ones include micro-fault, micro-liquefaction veinlets, pyroclastic crystals, and pseudomorphs of tuff glass etc. Earthquake shocking induced all of above events, which are interpreted in this paper as a result of volcanic eruption. Besides, there are abnormal geochemical records such as Re, Os, Ir as well as other rare elements in black silty mudstones or shales of the Chuanlinggou Formation. The geological event records in the Chuanlinggou Formation give a clue to interpret the interruption of so-called oldest metazoan trace fossils from the overlying Changzhougou Formation. Besides, this paper suggests that an authigenic rare earth element mineral-monazite might be found from the Chuanlinggou and Changzhougou Formations according to the anomalously high Ce content because the authigenic monazite has been already discovered from the Precambrian mudstone of the Dalian area. The discovery of authigenic monozite provides a possibility for isotopic age determination by using the U and Th-Pb methods. The authors of this paper hold that the Chuanlinggou Formation of the Ming Tombs District of Beijing corresponds to the upper part of the Chuanlinggou Formation of the Jixian section of Tianjin.
